Board wiper cleaning device

ABSTRACT

A cleaning device includes a box having a hole for a board wiper inserted in the box and a plurality of plates are connected between two opposite inner walls of the box. An opening is defined through the box and communicates with an interior of the box. A collection drawer is slidably received in the box via the opening. The board wiper is hit on the plates and chalk powder drop in the collection drawer. Two brushes are connected to one of the inner sides of the box for further cleaning the wipers.

FIELD OF THE INVENTION

[0001] The present invention relates to a cleaning device for boardwipers and includes a plurality of plates connected between two oppositewalls of a box and a collection drawer is located below the plates tocollect the chalk powder.

BACKGROUND OF THE INVENTION

[0002] A conventional board wiper cleaning device 70 for removing chalkpowder from the wipers is shown in FIG. 6 and generally includes a box71 having an open top which is closed by a cover 74, and a bristledevice 73 received in the box 71. A crank 72 is accessed from outside ofthe box 71 and connected to a shaft 75 on which the bristle device 73 isconnected. When rotating the crank 72, the shaft 75 and the bristledevice 73 are rotated and the user inserts the board wiper 60 in the box71 to let the bristle device 73 wipe the chalk powder from the wiper 60.Because the cover 74 has to be lifted to let the wiper 60 inserted inthe box 71 so that the chalk powder removed from the wiper 60 could flyout from the top opening of the box 71. Besides, the user holds thewiper 60 by one hand and the other hand rotates the crank 72, thisoperation process makes the user's head close to the top opening of thebox 71. It is harm to our health if we absorb too many chalk powderparticles.

[0003] The present invention intends to provide a board wiper cleaningdevice which effectively removes chalk powder from the wipers and thecleaning device has a closed top.

SUMMARY OF THE INVENTION

[0004] In accordance with one aspect of the present invention, there isprovided a cleaning device and comprises a box having a hole definedthrough a side thereof and a plurality of plates are connected betweentwo opposite inner walls of the box. An opening is defined through thebox for a collection drawer being slidably received in the box.

[0005] The primary object of the present invention is to provide a boardwiper cleaning device that has an enclosed box and plates connectedtherein so that the wipers are hit on the plates to effectively removethe chalk powder.

[0006] These and further objects, features and advantages of the presentinvention will become more obvious from the following description whentaken in connection with the accompanying drawings which show, forpurposes of illustration only, several embodiments in accordance withthe present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] Referring to FIGS. 1 and 2, the board wiper cleaning device ofthe present invention comprises a box 10 having a hole 12 definedthrough a side thereof and two boards 11 are respectively connected totwo opposite inner walls of the box 10. The box 10 has a closed top by atop board 50. A plurality of plates 31 are connected between the twoboards 11. Each board 11 has a plurality of notches 111 defined in a topedge thereof so that two ends of each of the plates 31 are engaged withtwo respective notches 111 in the two boards 11. The notches 111 aresized wider than a thickness of the plates 31 so that when a board wiper60 is inserted into the box 10 via the hole 12, it is hit on the topedges of the plates 31 as shown in FIG. 4 to drop the chalk powder onthe wiper 60. The plates 31 may shake and jump up and down because thenotches 111 is wider than the thickness of the plates 31 so that chalkpowder on the plates 31 easily drops too.

[0014] An opening 13 is defined through the box 10 and communicates withan interior of the box 10 so that a collection drawer 20 is slidablyreceived in the box 10 via the opening 13. The chalk powder drop fromthe wiper 60 is collected in the collection drawer 20. The collectiondrawer 20 has a handle 21 for convenience of being pulled out from thebox 10. As shown in FIGS. 3 and 5, two brushes 41 are connected to oneof the two inner walls as shown in FIGS. 3 and 5. The brushes 41 areused to further clean the wipers 60 by scrubbing the wipers 60 on thebristles 411 of the brushes 41.

[0015] There is only one hole 12 in the box 10 so that the chalk powderwill not fly out of the box 10. The plates 31 have a thin top edge sothat when hitting the wipers 60, the chalk powder is easily shank downfrom the wipers 60.

[0016] While we have shown and described various embodiments inaccordance with the present invention, it should be clear to thoseskilled in the art that further embodiments may be made withoutdeparting from the scope and spirit of the present invention.
